    i am kind of new to javascript coding, and have been struggling with some code I assume should be quite simple to write: I created a text field, and i want to restrict its values to numeric ones. I started with making a validation to raise an error if the value entered is not a numneric value. That's the script i wrote on the "On Change" event of the field: 

    // JScript source code
var i = crmForm.all.new_test.DataValue 
// Check that the field is a number (no alphabetical values allowed)
if (isNaN(i))
{
alert('Please enter a number.');
crmForm.all.new_test.focus();
return false;
}

    If I enter an non-numeric value, the alert is raised, but I still can save the form. I tried to put the same validation on the onSave event of the form with no further success. 

    Any help would be appreciated !

    Hello Fadi,

    To restrict Save of form you should use following code at OnSave event handler:

     

    var i = crmForm.all.new_test.DataValue;
if (isNaN(i))
{
alert('Please enter a number.');
event.returnValue = false;
return false;
}

    Hi Fadi,

    Also if your textfield is a business required field you can just erase the data after alert message. So there would be no neccessity of on save event.

    if (isNaN(i))
    {
    alert('Please enter a number.'); //also can alert the user entered value if you want.
    crmForm.all.new_test.DataValue=null;

    }


    Regards,

    Thanks Andriy and Ravi for your help! 

    I used the combination of your suggestions: 

    if (isNaN(i))
{
alert('Please enter a number');
crmForm.all.new_test.DataValue=null;
event.returnValue = false;
return false;
}

    and got the exact behavior i was looking for: the field is emptied and the focus remains on the field itself!
